If I understand the question correctly, it can't be changed. There are 12 positions with 4 poles, each pole having 3 ways or contacts. The number of ways is fixed by the switches wiper geometry. However, the number of positions can be reduced using adjustable stop
It does appear that having the four pole, three way wafer the poles and corresponding contacts could be paralleled up to give 4 amp rating...... maybe
I think Mark needs 4 ways/positions so maybe only 3A?
I hope that I have my poles and ways the right way around
